The roll to roll flexographic printing machines with independent cylinders are in the " sPress" series. This series of machines is divided into 3 models each with different technical specifications such as, for example, maximum width and print speed. The "sPress 5" model is designed for narrow and medium printing widths. The "sPress 7" model is for medium and large printing widths. The transmission system of the inking units of this model is designed to ensure highly accurate synchronisation and, therefore, reliable maintenance of longitudinal displacement. The use of continuously variable transmissions (360°) permits extreme ease and speed of displacement of this machine during start-up. The "sPress 10" model is based on the "sPress 7" described above, but has a sturdier structure for greater printing widths.
